The Justice Department and the FBI are in discussions with lawyers for Huma Abedin to conduct a full search of new emails discovered on her husband's computer that turned up during another investigation, CNN reported Sunday.

Investigators believe it's likely the newly recovered trove will include emails that were deleted from Democratic presidential candidate Hillary Clinton's server before the FBI took possession of it as part of an earlier investigation that many thought had concluded in July, CNN reported.

The FBI still has not yet sought a search warrant for the emails, law enforcement sources told CNN.

Investigators need a search warrant to permit investigators to review thousands of emails on a computer Abedin shared with her estranged husband, Anthony Weiner, officials said.

The new search warrant is needed because investigators only had the authority to probe Weiner, who is accused of having sexually explicit communications with an underage girl.

The FBI's New York office stumbled on the Abedin emails while they were reviewing emails and other communications on the computer, which was considered to belong to Weiner, the officials told CNN.

They immediately ceased their work and called in the team of investigators from FBI headquarters who conducted the probe of Clinton's private email server. The investigators, based in the New York field office, saw enough of the emails to determine that they appeared pertinent to the previously completed investigation and that they may be emails not previously reviewed.

FBI Director James Comey's announcement of the new emails Friday rocked the news cycle just 11 days ahead of the presidential election and fueled Republican presidential candidate Donald Trump's claims that Clinton's conduct was illegal and "threatened the security of the United States."

But Clinton, who was cleared of any wrongdoing by the Justice Department in July during an FBI probe into how she handled sensitive information, is complaining that Comey released few details about the new information.

Yahoo originally reported that since FBI agents have not gotten the chance to read any of the emails, they are "still in the dark about whether they include any classified material that "the bureau has not already seen."

Clinton's campaign on Sunday pressured Comey to release more details about the emails he says could be related to the investigation into her use of a private email server, including whether Comey had even reviewed them himself.

Tim Kaine, Clinton's running mate, said Comey owed it to the public to be more forthcoming about the emails under review by the FBI with only 10 days remaining before Nov. 8 election. Kaine's message aimed to counter Republican rival Donald Trump, who has seized on the reignited email controversy in hopes of sewing fresh doubts about Clinton's trustworthiness.

"As far as we know now, Director Comey knows nothing about the content of these emails. We don't know whether they're to or from Hillary at all," said Kaine, who called Comey's announcement "extremely puzzling." The Virginia senator said if Comey "hasn't seen the emails, I mean they need to make that completely plain. Then they should work to see the emails and release the circumstances of those once they have done that analysis."

Clinton's campaign chairman, John Podesta, said Comey's handling of the matter was "inappropriate." Podesta urged Comey to be more transparent because the disclosure came "in the middle of the presidential campaign so close to the voting."

Clinton, speaking at a predominantly black church in Fort Lauderdale, Florida, did not mention the FBI inquiry but said Scripture reminded them that "suffering produces endurance and endurance produces character and character produces hope." Trump visited a nondenominational church in Las Vegas, where he swayed and clapped along to the music.

Comey's actions Friday roiled the White House race, energizing Trump as polls had showed him sliding and unnerving Democrats worried about the presidency and down-ballot congressional races.

Clinton's team tried to make its case on the Sunday news shows, joining Democratic leaders who have said it was "unprecedented" for such FBI action so close to an election.

Her campaign has called on Comey to release all the facts known so far, and they have criticized his letter because, they contend, it lacks crucial details.

Trump campaign manager Kellyanne Conway said Comey was in "an impossible spot" when he acknowledged the FBI was looking into the messages. "Had he sat on the information, one can argue that he also would be interfering in the election," by failing to disclose the review, Conway said.

Clinton said in Florida on Saturday that it was "pretty strange to put something like that out with such little information right before an election" and accused Trump of using the issue to mislead voters in the final leg of the campaign.

Trump told a crowd in Golden, Colorado, on Saturday that the FBI's review of Clinton email practices raises "everybody's deepest hope that justice, as last, can be properly delivered." His crowd cheered Clinton's email woes, which Trump has taken to calling the biggest political scandal since Watergate.

The controversy over Clinton's email practices while she served as secretary of State has dogged her for more than a year.

Late Saturday, four senior Democratic senators urged the Justice Department and the FBI to provide more detailed information by Monday about what investigative steps are being taken, the number of emails involved and what is being done to determine how many of the emails are duplicates of those already reviewed by the FBI.

The letter went to Comey and Attorney General Loretta Lynch from Sens. Ben Cardin of Maryland, Tom Carper of Delaware, Patrick Leahy of Vermont and Dianne Feinstein of California.

Comey spoke Saturday with the Republican and Democratic leaders of the House Judiciary Committee, said Chairman Bob Goodlatte, R-Va.

Goodlatte said he and Rep. John Conyers, D-Mich., encouraged Comey to make as much information as possible public before the election. He said the FBI chief "did not give us any response in terms of what more he could say."

Goodlatte said he also asked Comey about the status of the request from the House Republicans on the referral "of potential impeachment — I'm sorry — potential perjury charges to be brought with regard to Ms. Clinton and he deferred to the Justice Department itself. He did not answer that question as well."

The slip about impeachment reflected the GOP promise, if Clinton is elected, to doggedly investigate her.

A government official told The Associated Press on Saturday that the Justice Department had advised the FBI against telling Congress about the new developments in the Clinton investigation because of the potential fallout so close to the election. The official was not authorized to speak publicly about the matter and discussed it on condition of anonymity.

Justice officials concluded the letter would be inconsistent with department policy that directs against investigative actions that could be seen as affecting an election or helping a particular candidate, the official said.

Kaine and Goodlatte appeared on ABC's "This Week," Podesta and Conway were on CNN's "State of the Union"
